Aloha to all. Inverted "L" up and running.   Yep 30 ft up, than 100 ft., coiled in the the "Attic".  With end of the radiator (wire) at the highest point.  I'll remove the test feedline and cut the LMR400 to frequency.
                           

                               492 X 86%     (The top numbers Divided by the frequency)
     Ans?  Equals          1.820.00 Mhz

If needed radials 60 ft each leg of 6 each.  Or 6 or more of #14 gauge strandand radials at 130 ft.  Instead of cutting your radiator.  Cut the coax/feedline to the frequency that you would normally talk on SSB.

The last Inverted "L" is used #10 gauge stranded coated wire for the radiator, then 2 spools of #16 gauge stranded coated and pink or purple.  It was cheap too, hi hi. And the feedline I use some old mili spec RG213 short length.  The ground side of the feedline was tapped onto the 8 ft ground rod than the 22 radials attached, spread out away from the feed point, wrapped around the property or out towards the alley and front of the house.  Roll Eyes

"Are ready for 160 meters"? ? ?

Additional note:  35.000 ft of LMR400 cut to frequency.  RF Choke added at the feed point...

Additional Info of the Inverted L:  The feed point is about three foot off the ground.  Reason, lolo me should have anchored the feed point first and then proceed on tacking the radiator in the attic.   Frequencies from 1.800.00 to 1.910.00 mhz measured 1:1.1 to 1:3.1. With pwr output of 200 watts from the FT857D Yaesu.
Also the tuner was added for other bands with the exceptions of 40 Meters. I don't know why but the antenna tuners I have would not tune on that frequency.  Two "no radials" but just an eight foot ground rod to anchor the antenna in place.
See you all laters  Wade
